My New Macbook Pro

tbh, I like ML better than Lion.
Lion had so many bugs during launch and even at 10.7.4, it was heavy.
In ML, boot time got cut down by couple seconds, consumes less memory, and I believe they are faster.

 

Nope 2012 MBP's Optical drive bay is only upto SATA II.
This has been discussed in the previous forum and is identified as SATA II.

 

Well, if you have the cash and dont need that much space go for 3G SSD.
I just need more space so I go with 1TB HDD, soon replacing it with 2TB.

 

Have the same machine you do--the bare bones one, though. ML runs great on this machine; it feels... smoother? than Lion. I'd get it. Don't you qualify for the free upgrade?

 

Congrats on the machine… but please post everything next time in one post, instead of four

 

I would say just get the 6G one since it will be harder to find the 3G and the prices might not be that much lower. Up to you of course.

 

I agree. And also for more future longevity.

 

Interesting... because I'm looking at System Info right now and both my HDD and SuperDrive's Link Speed are at 6 Gigabit (SATA III)

 

They are. But optibay cannot support it.

 

What do you mean? An optibay just forwards the SATA connection into a compatible "slot" for the HDD so it can fit. I don't think it has anything to do with transfer speed. Considering the controller for both SATA III ports are the same, the macbook shouldn't care whether or not there is a superdrive. As long as it's concerned, there are two slots for two SATA III devices.

 

SATA III in optibay would require batter cable, and better shielding because SATA III uses higher frequencies.

 

I don't know where you are pulling this information from because it doesn't make any sense. A cable is a cable; a bunch of metal rods/strips tied together that carry electrical current. Obviously if Apple added SATA III support to both ports in the notebook, surely it makes sense that SATA III devices would then work with these ports. And like I said earlier, an optibay doesn't affect the transfer speeds. It simply provides a mold for a 2.5" drive and directly forwards the data between the macbook and the drive. Ever wonder why caddies are so cheap on eBay? It's because they're very inexpensive to manufacture. A few plates of metal and plastic, and a SATA/power connector and you're good to go. There is no need for "special" SATA cables as they all do the same thing.
